I don't think that you will get a reasonable answer from the Microsoft support forums. I've tried there myself any number of times and you only get generic answers unless they have a fix.
In the case of both SkyDrive and SkyDrive Pro (part of the Office 365 SharePoint Online service), sync failures are no uncommon.
There are a number of things that might fix the issue. The most common is for the authentication to have a fit. Re-authenticating can be troublesome and may require you to mess around in the various places authentication can happen. In your case, this might include the browser (IE), MS Office and Windows 8 itself.
You might also have hit a file type that SkyDrive will not sync. SkyDrive is NOT DropBox even though the features seem similar initially. Try removing the offending files to a non-sync'd folder, ensure that sync is working OK then put them back one at a time. SkyDrive cannot sync certain file extensions and has a file name limit - 256 I think - that INCLUDES the whole URL.
I've not had this problem myself with SkyDrive, but we do get similar problems regularly with SkyDrive Pro. In that case, often the only way to get things working again is to remove all of the sync'd folders and start again. So the final approach for you would be to disconnect W8 from your SkyDrive, reboot then reconnect it again.
Sorry this is not a definitive answer but I'm afraid that MS have never been that good at writing sync systems. You will find vast arrays of information regarding problems with previous attempts such as ActiveSync, Offline folder sync, Briefcase, etc.
No, I am afraid it is not possible.
The quote below is from Microsoft's official website:
OneDrive desktop app functionality is built into Windows 8.1. If you
install the desktop app on a PC running Windows 8.1, Setup won't
appear. A setting will be installed that lets you use Office to work
on OneDrive documents with other people at the same time, but no other
features will be installed. For help with OneDrive in Windows 8.1 and
Windows RT 8.1, see OneDrive: FAQ.
I researched this some time ago and ended up leaving using Skydrive and began using Dropbox instead, for the same reason you mentioned.

ok, the SkyDrive application crashes because of an failed ASSERT
This statement causes the issue:
So there is an issue with the connection to the server. Make sure that app can connect to the Internet.
You should also report it in the MS forums (Technet, Answers), so that the Windows team can fix it if your PC works fine and has proper Internet Access.
